Question 1.
What is thermal desorption used for?
Show hintHide hint
Think about the compounds that evaporate easily.
Question 2.
Define passive sampling.
Show hintHide hint
Consider what it means to sample without actively drawing in material.
3Question 3.
What is the primary purpose of thermal desorption?
- To chemically analyze solid samples
- To quickly release VOCs for analysis
- To collect liquid samples
Show hintHide hint
Think about the process of heating samples.
4Question 4.

- True
- False
Show hintHide hint
Remember the definition of passive sampling.
Question 5.
Design a comprehensive air quality monitoring plan that incorporates both active and passive sampling methods. Discuss the benefits and challenges of each approach.
Show hintHide hint
Consider how you can combine the strengths of both methods.
Question 6.
